STRUCTURE FOR USE AS STENCIL-CARD.

To all rrhom it may concern:

lle it known that I, Enwm D.'BELKNAP, a citizen of the lnited States ofAmerica, residing at East Orange, county of Essex, State of New.lersey,'have invented certain new and useful Improvements in Structuresfor Use as Stencil-Cards, of which the fol- 7 In the production of suchstencil cards certain conflictingconditions have to be neutralized. Thatis to say, the stencil card must have a certain stiffness sutlicient toenable it to he handled rapidly by a feeding apparatus in the printingmachine without thecards buckling; and at the same time the framesemployed to give the card this stiffness must have an ai'ipre'ciahlethickness so that the cards may he fed forward in a series edgcto edge,one propelling, another along a slottedguideway. without danger of theedges overlapping and one card sliding over or partly \vedging underanother. while at the same time the blank which is to he stciicilizedmust have suflicieii't flexibility and consequent thinness to permit itto readily adapt itself to the curvature. of the platen of the t\'pe\vri tiiig machine upon which it is stcncilizcd. Also, it isdesirable that the frame of the stencil card shall have a projectingportion aloiigone edge upon which various indexing marks and record datamay he placed and such extension in terferes with the convenientmanipulation of the ard in a typewriting machine.

My invention overcomes these ditliculties and produces a structure whichin its combined and constituent'elements has all of these variousqualities to the highest degree during the different steps of thetreatment above outlined, without any one interfering with the other.

The best form of apparatus embodying my invention at present known to meis illustrated in the accompanying sheet of drawings in which Figure 1is a face view of the completed card; Fig. 2 is asimilar View of thesame Specification of Letters Patent.

Throughout the drawings like reference characters indicate like parts.

1 and 2, represent sheets of material such as stiff paper or thincardboard which are duplicates one of another. Each is of substantiallyrectangular shape and has substantially rectangular openings which, whenthe two sheets are superposed, register one with another to form anopening 7. The

two cardboard sheets 1 and 2, are preferably fastened together by cementand the narrow strip 3, of paper, cardboard or other spacing material.along all their edges except for a space left open to form a slitopposite one end of the opening 7. This unfilled space is long enough topermit the insertion and withdrawal of a blank or stencilized cardcomposed of the rectangular frame 5 of coin mratively thin and flexiblematerial and the sheet 6 of parchment or treated paper adapted to bestencilized by perforation or by type pressure such as described inLetters latent'Xo. 1,110,869 to F..D. and E. l). Ilelknap. datedSeptember .1? 1914, and similar patents, cemented thereto.- As thisunccmentcd space is'sljghtly longer than the frame 5 is wide, and frame5 is wider than opening 7. it follows. that this unfilled or unccmentcdspace is somewhat longer than that dimension of opening 7, which isparallel tothe unfilled or mice nicnted or uiifastened edges. Thisflexible card is of such length that when the same is pushed homethrough this opening. it occupies the position shown in Fig. 1, theinner outlines of its frame 5, approximating the outlines of theopenings 7, in the sheets 1 and 2. I

Preferably the edges of sheets 1 and 2, opposite one end of the opening7, and within the space not filled by the spacing strip 3, haveregistering arc-shaped cut-away portions 1, through which a portion ofthe end of the tlexibleframe 5, is exposed. Preferably also, theextension 8, of the main frame formed by the two sheets land 2, fastenedtogether as above described, is treated with some one of the well knownpreparations, such as silicate compositions, which form a surface filmon which ink or lead pencil marks can readily be made and from whichthey can be erased withequal readiness.

by the. flexible frame and treated or parchment sheet (3 may be removedfrom the containing frame by grasping one end of frame where it isexposed through the cutaway portions 4, and withdrawing it from theframe in the manner indicated in Fig. of the drawings, .and saidflexible inner card can then be conveniently manipulated in an ordinaryt'ypewriting machine to stencilize same, the flexible frame read i l yassuming the necessary curvature required to enable it-to lie closetothe typewriter platen. After the blank is stencilized and formed intoastencil cari'h-it is then rein sertedin the stiff, frame formed by thesheets 1 and 2 and spacing strip 3, and can be readily employedin theordinary stencil address printing inacliineJ TAt the same time anydesired indexing matter or other data' regarding the. customer whosename and address is stencilized upon the inner sheet may be marked uponthe treated surface of-the extension 8, of the outer frame and later, ifdesire(l, -all or a portion of these marks may be readily erased andmore .up-todate records and data substituted.

- A further advantage of the invention arises from the fact thatdifferent stencil blanks may be employed in the one frame! Thus, forinstance, in the case of a bnsines's'fifin openingan account with a newcustomer or merely sending advertising matter to a prospective Customerapart of the, initial expense" can be saved by using. a cheap parchmentstencilmaterial through which the name ,and address perforated .by theold fashipned perforating type and then'later if the lar customer, in'correspondence withwhom a morefini shed typegof address or billing mayestroyed and -."the' -mo're' modern card pr "usingtbe facsimiletypewriter stencil maybeemployed.
